6 Claims.

This invention relates to dividing strips for terrazzo or similar fioorings and has for a primary object, the provision of improvements in such a strip which will render the same susceptible of manufacture through the process of. extrusion or casting, so as to afford laterally projec'ting anchoring ledges and gauge shoulders that will have specific relation to the thicker portion of' the strip, to the end that abutting strips extending perpendicularly from the sides of the first mentioned strip may have a number of hearing faces" arranged in a common plane, which is substantially parallel to the comparatively thin body of the strip itself.

An'other 'aim of this invention isv to provide a'dividing barof the character just mentioned which includes anchoring ledges formed along the lowermost edge of the body of the bar and having extended therefrom, inclined faces which merge to create a sharpened edge which renders insertion'of the bar less troublesome and more effective with respect to displacing the cementitious material through which the lower portion of the dividing bar must be moved when positioning the same. I

An even further object of this invention is the provision of a dividing bar having a thicker portion along one longitudinal edge thereof and a plurality of laterally extended shoulders on ledges between said thicker portion and other edge of the'bar, and a shelf in close proximity to the said thicker portion, extending laterally from the body of the bar to provide a surface upon which a floor covering may rest.

Other objects of the invention which will include specific structural details of a novel nature, will appearduring the course of the following specification, referring to' the accompanying drawing, wherein severalmodified forms of a dividing bar are illustrated as exemplifications of the broad invention. In the drawing:

Fig. 1 is a fragmentary, perspective view of a dividing bar made in accordance with this'invention.

Fig. 2 is a similar view of another form of bar embodying the invention. Fig. 3 is a perspective view of a modified form of bar made to embody the invention. Figs. 4, 5 and 6 are vertical, cross sectional views through the bars shown in Figs. 1 2 and3 respectively, and with the bars in position in a terrazzo and cement flooring.

1 Figs; 7 and 8 are cross sectional views through the form of bar shown in Figs. 2 and 3 respectively, and illustrating the manner in which bars of a similar form might have their ends moved into abutting relation with the sides of the bar.

Figs. 9, 10, 11, 12, 13 and 14 are each illustrations of dividing bars embodying the invention, but each being of a different form from the other.

Dividing bars of the character forming the subject matter of this invention are usually po sitioned in a cement orscreed underbed l6 before the same sets. The insertion of the bar is accomplished by forcing one of the longitudinal edges thereof into the bed Hi to adesired depth. It is an advantage for bars of this type to have a gauge of some sort formed thereon which will clearly indicate to the workman when the bar has been placed properly. This gauge, when employed, will allow the right amount of the bar to project upwardly from underbed I B so that terrazzo cement [,8 will be of the proper depth when laid. m

In some cases, a linoleum, rubber tile, or composition fiooring 20"is set into the flooring and when such is the case, the form of bar illustrated in Figs. 1 and 4 serves to an advantage. This bar, like those hereinafter described, comprises a comparatively thin body22 of uniform thickness, which has a thicker portion 24 formed along one longitudinal edge thereof serving as the top of the bar when the same is in place; An anchoring ledge 26 extending laterally from one side of body 22 is disposed longitudinally along the bottom edge of the bar itself, and this bottom edge is sharp,'as shown, to facilitate in-' sertion.

A certain amount of lateral displacement is necessary when moving the bar to position, and the inclined face 28, which continues from the sharpened lower edge of the bar upwardly to the outer edge of ledge 26, is an efi'ective medium for accomplishing this displacement of cement underbed IS. A depth gauge in the form of a laterally extending shoulder 30 extends longitudinally along the bar intermediate the thickened portion 24 and ledge 26. Projections 26 and 30 in this form of the bar are along one side" of the latter and terminate in substantially the same plane as the side of thickened portion 24. This plane is parallel to the plane of body 22. A shelf 32 is formed along the other side of body 22 immediately beneath thicker portion 24. A groove 34, arcuate in cross section, is formed along the zone of connection between thickened portion 25 and shelf 32, and when the floor covering 20 is laid, this groove will accommodate any'projecting rough edged or frayed base material.

The form of bar illustrated in Figs. 2 and 5 is precisely the same as that form illustrated in Figs. 1 and 4, but with the elimination or omission of shelf 32. The side of body 22 opposite from projections 26 and 30 lies in a plane which will permit a straight end of another section 0 the bar to lie snugly thereagainst.

The form of bar exemplified in Figs. 3 and 6 is slightly different than those previously described and has a body 36 with a thickened portion 38 along the longitudinal top edge thereof. The

' lower or opposite edge of body 36 is substantially V-shaped in cross section to provide a sharp lower edge, adjacent which is a pair of opposed,

laterally extending ledges 40. The outer edges of these ledges 40 is in the same plane as the outermost surfaces of the bar thereabove and shoulder 42 serves as a depth gauge, as does shoulder in the other forms. bar made in accordance with the forms shown in Figs. 3 and 6, the cementitious underbed I6 is displaced laterally to each side of the body 36 as the sharpened edge is moved downwardly. By compressing underbed l6 in this fashion it will be caused to move back into position over the top of ledges 40 in an even more compact manner. It is notable that these ledges 26 and 40 are as low as possible and no smooth part of the bodies of the bars extend below the ledges as so much unnecessary material. Y

Figs. 7 and 8 show distinctly the manner in which the ends of bodies 22 and 36 respectively will lie against the laterally projected points and the smooth faces of the bar at a point of abutment.

Figs. 9 and 10 are bars of the extruded metal type with comparatively thin bodies 44 and 46 respectively, having thickened portions 48 and 50 respectively. In the case of Fig. 9, the thickened portion extends to each side of the thin body 44, while the bar illustrated in Fig. 10 has a thickened portion extending to but one side of body 46. A longitudinal embossment 52 is created in body 44 and the outermost face of this embossment is in a plane with the overlying edge of head 48. A similar embossment 54 is'formed longitudinally along body 46 and the outermost face of this embossment 54 is in a plane with the outermost overlying face of thickened portion 50.

Fig. 12 is a bar similar to that shown in Fig. 10 in so far as its comparatively thin body and thickened portion 56 and 58 respectively are concerned. A sharpened longitudinal edge 60 is created along the lower edge of body 56 and a laterally extending anchoring ledge 62 is formed comparatively close to this edge 60. The inclined face 64 which joins edge 60 and .the outer edge of ledge 62 serves to displace the screed underbed when the bar is being inserted, as hereinbefore described.

Figs. 11 and 13 illustrate a dividing bar of substantially like characteristics in that each has a comparatively thin body 66 having a thickened portion'68 thereon and a sharp lower edge 10 with opposed, laterally extending ledges 12 along each side of the bar that meet inclined faces 14 which diverge from sharpened edge"). In the case of the bar illustrated in Fig. 11, after extrusion it is provided with outwardly punched ears '6 which are formed from body 66. These ears supplement the anchoring action of ledges 12.

The bar shown in Fig. 14 has a thin body 18, with a'thickened head or edge portion 80 along one of its longitudinal edges; corrugations 82 provide the transverse or laterally disposed an- In placing the choring ledges to preclude lifting of the bar from underbed l6 and likewise to indicate the depth to which the bar is to be inserted.

All of the forms of dividing bars illustrated width having a thicker portion along one longitudinal edge thereof serving as the top of the 7 bar when in place; formed along the side of said body with its outer edge in substantially the same plane as the overlying outer edge of said thickened portion, said plane being parallel with the major plane of the body of the dividing bar.

2.'A dividing bar of the character described comprising a comparatively thin body of uniform Width having a thicker portion along one'longitudinal edge thereof serving as the top of the bar when in place and having a planar upper surface; an anchoring ledge formed along the side of said body at the other edge thereof and a laterally disposed; longitudinally extending shoulder formed on the body along the side thereof intermediate said top and the anchoring ledge, the outer edges of said thickened .top, anchoring ledge and shoulder being in a plane perpendicular to said planar surface to present bearing the bar when the same is in place; an anchoring ledge. formed along one side of said body at the other edge thereof; a laterally disposed longitudinally extending shoulder formed on the body along the saidone side thereof intermediate the said top and the anchoring ledge; and a shelf projecting laterally from the other side of the body and extending longitudinally therealong' immediately beneath the said thickened portion, one side of the thickened portion and the outer edges of the anchoring ledge and shoulder being in a common plane parallel to the proximal side of the said body, the other side of the thickened portion and other side of the body being in a common plane parallel with said first mentioned common plane, said shelf extending laterally beyond the last mentioned plane. Y

4. A dividing bar of the character described comprising a comparatively thin body of uniform width having a thicker portion along one longitudinal edge thereof serving as the top of the bar; and a wider portion along the other longitudinal edge of the body forming a laterally projecting anchoring ledge parallel to and comparatively close to the said last mentioned edge of the body, said wider portion being V-shaped in transverse cross section whereby to present a sharp entering edge and a ledge along the lower edge of the body. 7

-5.'A dividing bar of the character described 'comprising a comparatively thin body having a thicker portion along one longitudinal edge thereof serving as the top of the bar, and a laterally extendin shoulder formed along the other and an anchoring ledge of serving as the top of the bar; and a sharp edge formed along the other edge of the body, the

margins along each side of the body at the sharp V edge diverging upwardly and outwardly, and each terminating at a longitudinally extending lateral anchoring ledge disposed substantially perpendicularly to the proximal adjacent side of the said body.
